Abstract

A temperature-sensing device configured to monitor a temperature is disclosed. The temperature-sensing device includes: a first capacitor comprising a first oxide layer with a first thickness; a second capacitor comprising a second oxide layer with a second thickness, wherein the second thickness of the second oxide layer is different from the first thickness of the first oxide layer; and a control logic circuit, coupled to the first and second capacitors, and configured to determine whether the monitored temperature is equal to or greater than a threshold temperature based on whether at least one of the first and second oxide layers breaks down.
